Title: Fix for inheritable settings in initializer

When trying to set inheritable settings on a namespace that was already
initialized, the block would not be run. In the end, this just meant
that you couldn't update settings on the default namespace.

This fixes the issue and adds specs to ensure it won't happen again.
